This project is a PC-based unreal engine based on PBR workflow design and development of practical, tactical next-generation flight simulation games. Scene construction aspects: There are two theme planes, the number of planes and the wiring are reasonable, the mapping adopts PBR process to make the mapping exquisite and reasonable in size, and the blueprint is in line with the kinematic law. The main buildings in the flight scene are the airport and airport-related operating facilities and auxiliary systems. Battlefield city clusters, enemy chariot troops, ship troops. Game simulation aspects: Flight simulation module: Players will use various types of jet aircraft from the 1960 s to the 1990 s to simulate flight. The simulated flight actions include taking off, landing, raising or lowering the throttle valve to control the forward speed of the aircraft, opening the afterburner to experience the flying feeling of extreme speed, etc. Through the guidance of simulated flight after various difficult flight actions such as Pugachev cobra maneuver, scissors cutting, falling leaves floating, etc. to carry out air combat; Players make correct flight tactics according to battlefield conditions. The flight simulation module is one of the main key modules in the design of this topic. Weapons and mission modules: players will be able to use cannons to fire at targets directly in front of them. Correctly use close-range combat infrared missiles and operate airborne radar to guide semi-active radar guided missiles to experience over-the-horizon combat. Use bombs and rockets to destroy targets such as tank anti-aircraft guns. Use interference strips, hot flame bombs, etc. to interfere with missiles tracking themselves to safely complete air-to-ground missions. Weapon and mission module is another key module in this design. Environment module: players will experience the battlefield environment based on real geographical features, and match the music and cutscenes in the background of the environment. Custom vehicle material system: the user can set the material of the selected vehicle according to personal preference. Through UE5 to make the next generation of air combat simulation game is to let the player incarnate as an ace driver, get an excellent simulation experience, and experience the fun of experiencing modern air combat in a real combat environment. Players can choose to control various types of jet aircraft from the 1960 s to the 1990 s, experience the joy of flight simulation, and experience maneuvering the aircraft in various environments. In the aircraft, players will be able to control weapons systems such as guns, missiles, bombs, and rockets to complete air-to-ground missions, support, and simulation missions. Operational areas include oceans, deserts, urban ultra-high altitude and other environments.
